For years, Gaubatz has warned that Muslims in this country form a kind of Fifth Column — and that President Barack Obama is part of this seditious group. (He’s also called Obama a “self admitted ‘crack-head.’”) Gaubatz’s book detailing these claims recently became an Amazon bestseller, its conclusions endorsed by a handful of Republican Congressmen.

When Maj. Nidal Hasan — a Muslim-American with links to religious radicals — killed 13 at Ft. Hood last week, Gaubatz renewed his call for a purge within the U.S. Islamic community:

Muslims know what materials are being taught in their mosques and they know many of the materials instruct young Muslims to kill innocent people who do not adhere to Sharia law. If Muslims do not want a backlash, then I would recommend a “house cleaning.” Stack every Saudi, al Qaeda, Pakistani, Taliban, Hamas, and Muslim Brotherhood piece of material from their mosque and have a bonfire. Tell the American, Jewish, and Muslim community this hatred will no longer be allowed in their mosques.

Of course, most U.S. Muslims don’t shoot up their fellow soldiers. Fine… You invent a jihadi-detector that works every time it’s used, and we’ll welcome you back with open arms.

Ironically, Hasan, the Ft. Hood shooter, made a similar argument in a 2007 presentation. In order to avoid “adverse events,” like Muslim troops deserting or turning on their fellow serrvicemembers, Hasan recommended giving “Muslim soldiers the option of being released as ‘conscientious objectors.’”

The U.S. military’s failure to understand the cultural and religious landscapes in Iraq and Afghanistan directly contributed to setbacks in those war efforts, top generals say. You can’t conduct a proper counterinsurgency if you don’t understand how the society you’re trying to protect. Purge the American armed forces of its Muslims, and that cultural isolation becomes only more acute. Hard-to-win campaigns become almost impossible. It kind of makes you wonder who the real Fifth Columnists are around here.

We don’t know if this is reason for hope, or just low comedy. But the right-wing think tank that published conservative author Dave Gaubatz’s call for a backlash against the “Muslim community” has now scrubbed the line and replaced it with a call for a backlash against the “Muslim Brotherhood.”

Here’s how the passage of the Fort Hood Q&A with Gaubatz, the author of Muslim Mafia, read on Monday (see a screengrab of the original here):

Politicians, Muslims, and law enforcement are concerned about a ‘backlash’ against Muslims. Now is the time for a professional and legal backlash against the Muslim community and their leaders. Muslims know what materials are being taught in their mosques and they know many of the materials instruct young Muslims to kill innocent people who do not adhere to Sharia law.And here’s the version that is currently up on FSM’s site:

Politicians, Muslims, and law enforcement are concerned about a ‘backlash’ against Muslims. Now is the time for a professional and legal backlash against the Muslim Brotherhood and their leaders. Muslims know what materials are being taught in their mosques and they know many of the materials instruct young Muslims to kill innocent people who do not adhere to Sharia law.Even on its own terms, the new passage doesn’t make a ton of sense, shifting from Muslims to Muslim Brotherhood and back to Muslims.

Several outlets picked up Gaubatz’s comments after they were first reported by TPMmuckraker.

FSM says its mission is to “empower all Americans to become proactive defenders of our national security and community safety.” Its board of advisors includes radio host Laura Ingraham, former Clinton CIA director Jim Woolsey, and GOP operative Barbara Comstock.
